When I start the nest application, then it successfully starts and shows the logs given below.

I've used mand npm run dev:start to start the project.

Now if I send any request to the end points, it successfully sends the request and data get stored in the database and also returns the data but the problem is code gets repiled and in console it displays

and it doesn't show the log messages. How can I fix this?

Add to your tsconfig.json:

"include": [
    "src"
]

If the above doesn't work, here is how i fixed the issue

This is something related with your OS (Windows 11 in my case) and ts 4.9

Try it out with typescript 4.8 instead, in the package.json include

"devDependencies": {
  ...,
  "typescript": "4.8.3",
  ...
}

later

npm i
npm run start:dev

This might help you: https://devblogs.microsoft./typescript/announcing-typescript-4-9/#file-watching-changes

As mentioned in NestJs Documentation in Windows operating system for Typescript version 9+ we need to add following after pilerOptions in tsconfig file:

"watchOptions": { "watchFile": "fixedPollingInterval" }

if the above doesn't work, here is how i fixed the issue

for NestJS

inside the : tsconfig.build.json file

Add "include": ["./src"]

Looks like this

tsconfig.build.json

{
      "extends": "./tsconfig.json",
      "exclude": ["node_modules", "test", "dist", "**/*spec.ts"],
      "include": ["./src"]
    }

i don't know which dependency caused the issue in my case. but for me it just worked after i ran:

npm audit fix
